DAVID FRANKLIN YOUNGBLOOD, OF SAN ANTONIO, TEXAS.

LOOKING AND OPERATING `SYS'lIElVI FOR CELL DOORS.

Original No. 1,611,260, dated December 21, 1926, Serial No. 97,281, led March 25, 1926. Application for reissue filed December 19, 1928. Serial No. 327,163.

This invention relates to a locking and operating system for cell doors, whereby the latter may be individually or collectively controlled by ya, prison attendant from a control box, usually located at the end or in frontof the' row of cells with which the system is associated.

The system to which the present invention relates is similar in many respects to that disclosed in U. S. Patent No. 1,269,214

issuedu to me June 11, 1918, but embodies a number of improvements thereon.

In the majority of large city jails and penitenitaries, it is usually desired to have a large number of cells, frequently sixteen or more, in one row. Vith the ordinaryr lever and straight travel bar, as disclosed in the abovementioned patent, itis not feasible to operate more than about eight doors. i i

One ofthe principal objects of the present invention, therefore, is toprovide an improved system which may' be successively used to operate, lock and unlock the Adoors of any desired number of cellsin` one row.

Other important objects of the invention will be explained in the following detailed description,` taken in connection with the accompanying drawings, which illustrate various embodiments of the invention. In the drawings: y

Figure 16 is a plan viewrof the mechanism shown in Figure 15, -thecasing and the wall in front of the corridor being shown in secp tion.

Figure 17 is a` plan View of the selective means used in connection with the mechanism illustrated inFigures 15 and 16.

Figure 18 is a transverse section through the door controlling mechanism as used in any of the forms illustrated in Figures 7 to 17 inclusive,

The various embodiments of the invention are illustrated in connection with a prison having a cell room 1, Within which is located a row of cells 2, each having a doorppening int-o a corridor 4. The cell doors are all controlled from a box 5 which, in the form illustrated in Figure 1, is located at the front end of the row of cells. rAs illustrated in Figures 2 to 5 inclusive, each door 3 is" supported by means of a hanger secured to its upper end, and extending upwardly through a slot 7 in a casingv 8 extending longitudinally of the row of cells above the doors.' The hanger'` 6 is secured to a carriage 9, which is located within thel casing 8, and has stub axles 10 secured theretowith the wheels 11 journaled thereon, and adapted to fride on a track 12 conveniently-made of a structuraly angle. A bar 123 is securedjo the carriage 9 within the casing and covers-the slot 7 to prevent unauthorized access to the mechanism.

Each door 3 is provided near the top and bottom with keepers in the form of bars 14, each having notches 15 for the reception of a lock bar 16, movable through a suitable lprotecting' casing 17, such as is frequently used in' jail door constructions and requires no special description. The purpose of the casing 17 is, of course, to shield the lock bar 16 from access by prisoners. Each lock bar 16 is hung from'one end of a' bell vcrank lever 18, whichlis shown as in the form. of a triangular plate, although such particular construction is not obligatory. The lever 18 is pivotally 'sup ported by a Vpivot pin 19 Within the casing 8, and the end of the lever opposite to that connected to the lock bar 16' is pivotally connected to vo ne endL of a'latch 20, whichV is supported and guided in a slot 21, formed 20 1n a bracket 22 secured4 to the side of the casing 8.A A lug23 is secured to one side ofthe latch 20, and the latch normally rests by gravity at the bottom of the slot 21, with the lug 23 engaging a notchv 24 formed in a 25 bar 25, which extends for the entire length of the row of cells, and is supported for longitudinal movement upon rollers 26.

liVVhen the lug 23 engages the notch 24, and

Y the 'bar 25is stationary, thelatch 2O is held against longitudinall movement, the lever 18 remains stationary with the lock bar 16 vengaging one of the notches 15 and locking the door 3 either in open or closed position. The front end of the bar 25 is formed with' a rack 27, which is engaged by a pin'- ion 28 at the upper end` of a vertical shaft 29.k The shaft 29, as show in Figure 2,' is connected 'by Worm gearing 30 to a horizontal shaft `31, which extends forwardly into Jche control box 5, and is provided with a hand Wheel 32 for operating the same. It will be understood, therefore, that when all of thelatches 20 are in normal position, with the lugs 23 engaging the notches 24, the hand Wheel 32 may be rotated to move the bar 25 longitudinally, thereby rocking the `levers 18, and simultaneously locking or unlocking all of the cell doors. Moreover, the Worm gearing, 30 is self-locking so that the locking bar 16 cannot be moved without rotating the hand Wheel.

lWhen all of the cell doors are unlocked, kthey may be allg'openedor closed-simultaneously by mechanism which is also controlled from the box 5, so that the keeper does'not have togo in the corridor among the released prisoners. This mechansm is shown 1n Figs. 2 to 5 as including a4 longitudinal tubular shaft or bar 33, lwhich extends from 6.0 end to end of the row of cells,

ported and guided between concave rollers 34, mounted -in a bracket 35, secured to the carriage 9. The front end of the tubular shaft or bar 33 has arack 36 connected G5 therewith which meshes with Va ,pinion-37 secured to the upper end of a vertical shaft 38. This shaft 38 is connected by Worm gearing 39 to a horizontal shaft 40 which is provided With a friction pulley 41, adapt- Aed to be engaged by a'drive pulley A42,

driven by an electric motor 43. This motor is mounted for vertical movement, and may be raised by means of a foot lever 44 withvbar 33 Withthe respective cell doors, it is provided with a notch 46 above each door, the notch being normally engaged by Tan arm 47 secured to, a bar 48, Which'is pivotally connected to one of the stub axles 10. The bar 48 extends through a slot 49 in a bracket 50, which is secured to the latch 20. It will be understood, therefore, that the. arm 47 normally rests in the notch 46, but Will be raised out of the notchy Whenever the latch 20 is lifted to disengage the lug 23 from the notch 24. VVhenever it is desired, therefore, to leave one. of the cell doors locked while the remaining doors are opened, the latch 2O above said door is lifted, so that -said door will remain locked when the bar 25 vis moved longitudinally to unlock the other doors. At the same time, the arm 47 above said door is lifted from the lnotch 46, thus permitting all of the unlocked doors to be opened, While the other door remains closed.

For lifting the latches 20, Dit is preferred to provide electro-magnetic means such as a solenoid or electro-magnet 51, shown diagrammatically above'the front end of each latch. Each solenoid or electro-magnet is connected to an individual circuit 52, which may be closed lbymeans of a push button 53, locatedin -apanel 54 supported within the control box 5. Mechanism is also provided for actuating thelatches 20 manually in case of failure of the electric current.

This 'manually operable mea-ns 'comprises a bell crank "55 for each'latch, said bell crank being mounted on a pivot`56, and having a pin 57 engaging aslot 58' in the latch. The

slot 58 is providedrto allowsuiiicient longitudinal movement'v of the latch'- to lock or unlock the door in cas it is desired to do so. The end of the bell crank 55, remote from the pin 57, is connected by a rod 5 9 to an individual -lever 60, pivotally mounted in the box 5 behind the panel 54 and provided at its lower end with a pivoted pusher bar 61 having a notch 62, to engage the bottom edge of ar'slot in the panel, so that it may be la'tclied to hold the corresponding latch 2,0 in raised position. Each rod 59 has an expansile coil `spring 63 mounted thereon, and adapted to restore the bell crank and latch 20 to normal or latched position as soon as the latch 61 is released.

In the form shown in Figures 7, 8, 12, 13 and 18, each latch 20 is lifted in the same manner as heretofore described, either by means of a lsolenoid 51, or by the actuation of one of the levers 60. For moving the latches longitudinally, however, a metallic strip 6-/1 is provided in place of the bar 25, this strip being provided with notches 65 for engagement by the lugs 23 on the respective latches. The strip 64 is connected at its ends by sprocket chains 66 and`67 respectively, to the ends of a similar strip 68 to form an endless element, with the sprocket chains 66 and 67 passing over sprocket Wheels 69 and 70, respectively. The sprocket Wheel 70 is mounted on a vertical shaft 71 at the rear end of thel casing 8, While the sprocket Wheel 69 is secured to the shaft 29, which is .actuated in the same manner as hereinbefore described to move the metallic strip 64 and the latches engaged therewith in one direction or the other.

In Figs. 7 and 8, the mechanism for open-y f strip 72 is connected at its ends by sprocket chains 73 and 74, respectively, to the ends of a similar strip 75 to form an endless element, with said sprocket chains passing over sprocket Wheels 76 and 77, respectively. The sprocket Wheel 77 is mounted on a vertical shaft 78 at the rear end of the casing 8, While the sprocket Wheel 76 is secured to the shaft 38, which is actuated in the manner hereinbefore described for opening or closing the doors.

The bracket- 79 yis made somewhat wider than the bracket 22, and is provided with slots for guiding and supporting strips 68 and 75, Well as the latch 20. The bracket 80 also is provided With slots for receiving the strips G8 and 75, as Well as the bar 48. Y l

In the modification shown in Figures 9, 10 and 1l, which is also used in connection i -with theparts shown in Figul'fes 1?) and 18,

electrical power is dispensed with. 'The sprocket Wheel 69 is mounted ou a short shaft 81 in the front end of the casing' 8, and the strip 64 is moved longitudinally in either direction by means of a link 82, which connects the saine to a. hand lever 83, suitably mounted within the control box 5. The sprocket` wheel 7 6 is similarly mounted on a short shaft 8-'1 in the front end of the casing 8, and thesirip 72 is moved. longitudinally through the medium-of lazy tongs 85,

connected at one end tosaid strip, and at l is connected at one end, as at 88, to an interl mediate .pivot of thelazy tongs, and is connected at its other end to a hand lever 89 suitably mounted Within the control box 5. By means of the lazy tongs, the doors have .acomp'aratively Wide range of movement. v

In the form illustrated in Figures 141, 15, 16, and 17, Which is'also adapted to be used with the mechanism shown in Figure 18, all. of the mechanism is controlled from a box 9.0, located in .front of the row of cells, and substantially midway betweenthe ends thereof, A- casingv 91 extends from the box to thecasing 8. In this form, the strip 68 is replaced bya strip 92 formed in two sections, connected together by a rack bar 93, which meshes With a gear 911 secured to the end of a shaft 95 journaled Within the casing 91. The outer end of the shaft 95 is I connected by sprocket gearing 96 to a shaft 97 mounted Within the box 90,and having a hand Wheel 98 secured thereto vfor actuating the same.` In this fo-rm, the strip 72 is replaced by a strip 99, which is formed in tWo sections connectedl by a rack bar 100 whichl meshes Wit-h a gear 101, secured to a shaft 102 journaled Within the casing 91. The outer end of the shaft 102 is connected by sprocket gearing 103 to a shaft 104: mounted Within the box 90,A and provided with a hand Wheel 105.` A friction pulley 106 is also secured to the shaft 10ft, and is adapted to be actuated' in the same manner as the pulley 41, by means of a pulley 107 carried by an electric motor 108, Whichis adapted to be moved vertically by means of a foot lever 109, so as to drive the shaft 104, and thereby open or close the cell doors. In this form, instead of the rods 59 for lifting the latches, rods 110 are provided which extend toward the center of the casing 8, and are there connected with the ends cf the respective sprocket chains 111 which passr4 over sprocket Wheels 112, and are counected at their other ends to rods 118, extending through the casing 91 and ccnnected With levers 114, which are mounted in the same manner as the levers 60 behind, Ia panel 115, Within the box 90, and provided at their lower ends. with pusher bars 116. Push buttons 117v are also provided in the panel 115, and have the same function as the push buttons 53.

From the foregoing description, it will be understood that I have provided improved mechanism which may be used for controlling and actuating any number of cell doors,

either individually orcollectively, and bv 33 is of strong construction,`and is guided betweenthe rollers '34, so thatl it will not y buckle no matter howA much power 'it is necessary `to exert in order to open the doors. Where the metallic strips 64, 68, 82, 7 5, 92 or 99 are used, they cannot buckle, because they are actuated by pulling through the medium of the sprocket chainsv, 67, 73 and 74. The arrangement shown in Figures llto 17 inclusive, makes it .possible to pull half the doors from one side, and push or pull the other. half from the other side in a long rouT of cells. The positionof the controlling mechanism in front of the cells wailordsthe prison keeper an opportunity to see into all of the cells while opening or closingithe` doors. In small town or county jails, Where electric current is rfrequently unavailable, it may be preferredlto use the hand lever construction, as shown in F igures 9 and Il. ,By means of .the construction shown in the drawings, vallof the cell doors may be opened or closed, and locked or unlocked simultaneously, or anynumber or combination of selected doors may be operated simultaneously while the others re-- main fixed. e.

The various embodiments of the invention have been illustrated vin connection-with the most common type of prison construction, in which the cells are equipped with slidingl doors, but it is apparent that the invention may be readilyadapted for use in connection with any other type of prison construction.v It is also apparent that Vvarious modifications may be made in the general arrangement' of the mechanism and in the" specic details"thereof, withoutany material departure from the salient features of theinvention as defined in the claims.
